The hp2pretty package

hp2pretty is a rewrite of hp2ps, implemented in Haskell, with
the aims of being maintainable, with more flexible output, and
more beautiful output. Currently hp2pretty outputs Scalable
Vector Graphics (SVG) only, though PostScript (PS) is planned.
Also none (count'em) of hp2ps' options are implemented yet in
hp2pretty.

Usage has changed since the previous release:

hp2pretty *.hp

hp2pretty --uniform-scale=time *.hp

hp2pretty --uniform-scale=memory *.hp

hp2pretty --uniform-scale=both *.hp

Colours have also changed: now they are based on a hash of the
cost label, which should make colours have stable semantics
across program runs.
